Preferably, foam concrete obturator 2 is full of the cavity that profiled sheet 3 and U-shaped groove 1 surround jointly.
Preferably, the every general steel plate that forms U-shaped groove 1 is all connected and fixed with foam concrete obturator 2 by the peg 4 of many spaced sets.
Preferably, profiled sheet 3 adopts welding manner to be connected and fixed with the interface 5 of U-shaped groove 1.
Preferably, on profiled sheet 3, be evenly equipped with multiple projections outside U-shaped groove 1.
The technical scheme being provided by above-mentioned the utility model can be found out, the lightweight antiknock plate that the utility model embodiment provides has adopted the general steel plate with good strength and ductility to make U-shaped groove 1, and be welded on the top of U-shaped groove 1 to be evenly equipped with the profiled sheet 3 of multiple projections, adopt again lightweight, high strength, the foam concrete that antiknock energy absorption performance is good is filled U-shaped groove 1, U-shaped groove 1 is connected and fixed by many pegs 4 with foam concrete obturator 2 simultaneously, therefore this lightweight antiknock plate has formed a light weight, high strength, there is the Unified Global of good ductility and antiknock energy absorption performance, thereby this lightweight antiknock plate is in absorbing explosion energy to greatest extent, be difficult for producing fragment, effectively avoid the secondary disaster being produced by fragment, and then can be better for there being the building of requirement of explosion proof.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain other accompanying drawings according to these accompanying drawings.
The structural representation of the lightweight antiknock plate that Fig. 1 provides for the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to protection domain of the present utility model.
The lightweight antiknock plate below the utility model embodiment being provided is described in detail.
Embodiment mono-
As shown in Figure 1, a kind of lightweight antiknock plate, its concrete structure can comprise: the U-shaped groove 1 being surrounded by general steel plate, foam concrete obturator 2 and profiled sheet 3; Profiled sheet 3 is fixed on the top of U-shaped groove 1, and jointly surrounds a cavity with U-shaped groove 1; Foam concrete obturator 2 is filled in this cavity, and the general steel plate that forms U-shaped groove 1 is connected and fixed by many pegs 4 and foam concrete obturator 2.
Wherein, the specific embodiments of each parts of this lightweight antiknock plate can comprise:
(1) U-shaped groove 1: surrounded by general steel plate of the prior art; Compared with steel plate with holes, general steel plate has that intensity is higher, ductility is better, the feature such as convenient of drawing materials, and the U-shaped groove 1 therefore surrounding with general steel plate has good intensity and ductility, has good impact resistance under Blast Shock.
(2) foam concrete obturator 2: foam concrete is light weight not only, and intensity is high, and antiknock energy absorption performance is better; Obturator and general steel plate that foam concrete is made are combined as a whole, and can significantly improve the antiknock ability of this lightweight antiknock plate.
(3) profiled sheet 3: profiled sheet 3 adopts welding manner to be connected and fixed with the interface 5 of U-shaped groove 1, it is firmly overall closely that this can make this lightweight antiknock plate structurally form a connection, thereby improved this lightweight antiknock slab integral impact resistance; On profiled sheet 3, be preferably evenly equipped with multiple projections outside U-shaped groove 1, these projections have improved the integral extension of this lightweight antiknock plate, and under Blast Shock, the integral extension performance of this lightweight antiknock plate is resisted external impact to a certain degree enough well.
(4) foam concrete obturator 2 is preferably full of the cavity that profiled sheet 3 and U-shaped groove 1 surround jointly, it is compact that this not only can make the overall structure of this lightweight antiknock plate connect, and can make each position of this lightweight antiknock plate all have equal antiknock to subtract quick-fried ability.
(5) the every general steel plate that forms U-shaped groove 1 is all connected and fixed with foam concrete obturator 2 by the peg 4 of many spaced sets, this can make to have good bonding strength between foam concrete obturator 2 and U-shaped groove 1, thereby make general steel plate under Blast Shock, be difficult for flying out separately with the form of fragment, produce but can be fixed on foam concrete obturator 2, thereby can effectively avoid the secondary disaster being produced by fragment.
Further, the work flow of this lightweight antiknock plate is as follows: general steel plate is surrounded to U-shaped groove 1, and many pegs 4 are preset on general steel plate; Using this U-shaped groove 1 as mould, and add wherein foam concrete; In this U-shaped groove 1, fill it up with after foam concrete, profiled sheet 3 is added in to the top layer of foam concrete, and the both sides of profiled sheet 3 and U-shaped groove 1 are welded; By the time foam concrete condenses after moulding, can obtain the lightweight antiknock plate that the utility model embodiment provides.
As fully visible, the lightweight antiknock plate that the utility model embodiment provides has adopted the general steel plate with good strength and ductility to make U-shaped groove 1, and be welded on the top of U-shaped groove 1 to be evenly equipped with the profiled sheet 3 of multiple projections, adopt again lightweight, high strength, the foam concrete that antiknock energy absorption performance is good is filled U-shaped groove 1, U-shaped groove 1 is connected and fixed by many pegs 4 with foam concrete obturator 2 simultaneously, therefore this lightweight antiknock plate has formed a light weight, high strength, there is the Unified Global of good ductility and antiknock energy absorption performance, thereby this lightweight antiknock plate is in absorbing explosion energy to greatest extent, be difficult for producing fragment, effectively avoid the secondary disaster being produced by fragment, and then can be better for there being the building of requirement of explosion proof.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
